ATL107_11 September 1980

Section "2": Stations 294-308 (crossing ACC to Chile)

Sections

CTD salinity section
CTD sigma theta section
CTD theta section

Surface dynamic height and properties

Dynamic height relative to 3000 dbar
Dynamic height for all ATL107_11 sections
Surface oxygen saturation

Profiles (highlighting stations 296, 299, 300, 301, 302 with deep mixed layers)

Comment:
Bottle data: sampling is poor, salinities don't agree with CTD at all well CTD data: surface point or 2 is generally bad (salinity)

Comments:
302 is apparently the densest mixed and apparently deepest mixed layer.
302 has deepest penetration of high oxygen of the thick mixed layer stations.
299 is saltiest mixed layer. 299 is just adjacent to the first SAF.
299 is really the deepest mixed layer. (302 has two layers)
